Summary
Roper Rhodes RR745 is a thermostatic cartridge used in MK2 concentric Roper Rhodes Storm shower valves. It is the internal temperature control cartridge that regulates the mix of hot and cold water to help restore correct shower temperature performance.
This cartridge is used in both concealed and exposed MK2 concentric valves. A worn or scaled thermostatic cartridge can cause unstable outlet temperature reduced control over temperature setting or poor thermostatic response during use.
